This invention relates to windows of the type which, while not limited thereto, are particularly applicable to railway passenger cars.

Gne of the objects of the invention is to provide an improved window having upper and lower sashes that can be removed after installation.

Another object is to provide a window, having a movable sash and a fixed sash, with improved means permitting adjustment of the open position of the movable sash.

Other objects and advantages of lthe invention will be apparent from the following description taken in connection with the accompanying drawings wherein:

FIGURE 1 is an elevational View of a window embodying the invention which view is looking from the interior of the enclosure enclosed by the window;

FlGURES 2, 3 and 4 are sectional views taken along lines 2-2, 3 3 and 4-4 respectively, of FIGURE l;

FIGURE 5 is a fragmentary elevational View of the portion of the window enclosed in reference box 5 of FIGURE 1; and

FIGURE 6 is a fragmentary perspective view of a corner of the window frame prior to drilling the fastener holes, FIGURES 2-6 being on enlarged scales relative to that of FIGURE l for clarity of illustration.

Referring now to the drawings, the illustrated embodiment comprises a window mounted on a wall panel 1t) of an enclosure, such as the deadlight panel of a railway car, in a rectangular opening 11, the window comprising an upper sash 12, a lower sash 14 and a window frame 16.

Window frame 16 comprises a pair of side frame elements 18, a top frame element 20 and a bottom frame element 22 secured to panel 16 by a plurality of threaded fasteners 24 spaced around the frame. The corners of the frame elements are beveled and are welded or otherwise suitably secured to form miter joints that are covered by corner trim caps 26 held in place by fasteners 24, as shown, the corners being ground, as at 2S (FIG. 5), to present a rounded corner appearance.

Each of fasteners 24 comprises a flat head, internally threaded post 39 and a round head screw 32 screwed into post 30 so that the heads draw the frame 16 and panel together and thereby secure the frame. A rectangular annular gasket 34 is sandwiched and secured between frame 16 and panel 10.

Side elements 18 of frame 16 are vertical, parallel and elongated and have irregular cross sections. As best seen in FIGURES 4 and 6, each side frame element 18 comprises a U-shaped channel portion comprising a oase 35 and a pair of parallel anges 38 and 40, and an L- shaped portion comprising a base 42 and a flange 44. Flanges 3S, 40 and 44 lie in parallel planes and bases 36 and 42 lie in parallel planes that are perpendicular to the planes of the flanges. Side frame elements 18 are in bilateral symmetry about the vertical centerline of the window whereby the U-shaped channel portions open towards each other and receive sash 14 in a manner more fully described hereafter.

With reference to FIGURE 6, top frame element 2G has a cross section similar to that of each of side frame elements 1S and comprises a U-shaped portion having a base 36 and flanges 38 and 4t), and an L-shaped portion comprising a base 42 and ilange 44 that abut the corresponding elements of the side frame elements at the corners. However, in order to facilitate removal of sash 12 where clearances are small, flange 38 of element 29 can be cut back or ground away a slight distance, as shown, to provide suitable clearance.

Similarly, bottom frame element 22 comprises a U- shaped channel portion having a base 36, and flanges 3S and 49, and a base 42 that extends outwardly from flange 4u. Bottom frame element 22 is dissimilar in cross section from the other frame elements because it does not have any element corresponding to flanges 44, this being done to improve the external appearance of the window.

As best seen in FIGURES 2 4, the outside surface of flange 40 abuts gasket 34 so that base 42 extends through opening 11 whereby ange 44 lies in a plane outside of the plane of panel 10 adjacent opening 11.

Sash 14 comprises a window pane 46, a vinyl protective channel 43 of U-shaped cross section surrounding the edges of pane 46, a sash frame 50 around channel 48, and a plurality of spacer bars 52 between the bases of channel 48 and side frame 52 which facilitate fabrication of the sash frame into a rigid unit. The sash frame is rectangular and includes a horizontal removable channel 54 which extends across frame 16 and is connected at opposite ends, by fasteners 24, to side frame elements 18. Removal of these fasteners allows channel 54 to be lifted and removed thereby permitting removal of pane 46 and protective channel 48 along with the spacer bars 52 if desired. Thus, if the pane is broken, the protective channel can readily be removed, and a new pane, with a protective channel thereon, inserted.

Sash 14 is inserted in the lower end of the U-shaped channel portion of frame 16 whereby the sash frame 50 is embraced by flanges 38 and 40. The bottom edge of sash 14 rests on a spacer bar 52 secured by the fasteners which attach the lower end of the frame to the panel 10. The width of sash 14 is equal to or less than the average of the distance between the adjacent surfaces of bases 36 of side frame elements 1S plus the distance between adjacent edges of flanges 38 of side frame elements 18, to permit removal of the entire sash. The width of sash 14 is greater than the distance between the adjacent edges of flanges 38 of side frame elements 18 so that the sash, when centered, is retained in frame 16 between flanges 38 and 40 as previously indicated. The height of sash 14 is slightly over one-half the height of the frame opening defined by anges 38 in order to provide a completely enclosed window. A pair of vertical spacer bars 56 are disposed between opposite sides of sash 14 and the adjacent bases 36 and center sash 14 in frame 16.

In order to remove sash 14, the following procedure can be used. First, the fasteners connecting channel 54 to frame 16 are removed and channel 54 and the spacer bar beneath it are lifted and removed. Next, the fasteners which extend through one of spacer bars 56, for example the left spacer bar as viewed in FIGURE 1, are removed and the spacer bar is then lifted up and out of the space between sash 14 and frame 16. If necessary, some of the fasteners above sash 14 and the left spacer bar might have to be removed to provide suitable Clearance. Then, sash 14 is shifted to the left, that is towards the side of frame 16 from which the spacer bar has been removed, and raised slightly to permit the right side of sash 14 to be pivoted inwardly relative to the enclosure to clear flange 38 whereupon the entire sash can be slid slightly to the right and removed from the frame. To replace sash 14, the reverse of this procedure can be used.

Sash 12 includes a window pane 58, a protective channel 6i) surrounding the pane, spacer bars 62 and a sash frame 64. The width of sash 12 is slightly less than the distance between flanges 42 of side frame elements 18 so that sash 12 is free to slide vertically relative to the frame. Since the width between fianges or bases 42 is equal to or slightly less than the width between the adjacent edges of flanges 38, sash 12 can be freely inserted and removed through the opening defined by flanges 38.

The height of sash 12 is slightly greater than one-half the height of the frame opening so that when sash 12 is closed, the bottom edge thereof is positioned, as illustrated in FIGURE 2, outwardly of the upper edge of sash 14, whereby sash 14 retains the lower edge of sash 12 in place against direct inward movement thereof. The thickness of sash frame 50 is approximately equal to the distance between the adjacent surfaces of flanges 38 and 40 whereas the thickness of sash frame 64 is less than the depth of base 42 to provide a clearance between sashes 12 and 14. The outer surface of channel S4 has cemented thereto an elongated strip 66 of a pile fabric that forms a seal between the sashes.

The fasteners alongside of sash 12, when the sash is closed, are arranged in pairs wherein each fastener of each pair extends through a different one of side frame elements 18 and is located at the same height as the other fastener of the same pair. Means are provided for supporting sash 12 on these paired fasteners in order to allow movement of sash 12 between a plurality of vertical positions. In the illustrated embodiment, such means comprises a pair of horizontally aligned, elongated, laterally but oppositely movable bolts 68 and 70. Each bolt has an enlarged head slidably supported by a guide bracket 72 secured to sash frame 64 adjacent side frame element 18.

Furthermore, as best seen in FIGURE 3, each bolt has a thin shank that extends inwardly fromV the enlarged head and terminates at a handle 74, the shank being provided with a slot 76 which straddles a screw 78 that acts as a stop member limiting lateral movement of the bolt to the length of slot 76. Also mounted on sash frame 64 is a stop member Sti having a horizontal bore whose walls support a helical compression spring S2 having ends that bear against adjacent surfaces of handles 74 and bias bolts 68 and 76 apart.

With reference to FIGURE 5, each of the bolts has an end provided with a cam surface 84 which is set at such an angle that the sash can be raised without the necessity of actuating handles 74. Under such circumstances, fasteners 24 cam bolts 68 and 76) towards each other. The bottoms of the ends of the bolts are flat and rest on top of the fasteners when operatively engaged therewith.

Such construction is advantageous since if a support fastener becomes worn or damaged, it can be replaced without replacing the whole line of fasteners.

The thickness of the head of each bolt, as best seen in FIGURE 3, is slightly less than the distance between flanges 38 and 40 of side elements 18 so that the bolts are slidably received therebetween. The clearance thus provided is relatively small to thereby minimize any rattle between the sash and frame. In this connection, it might be noticed that the clearance between sashes 12 and 14 is relatively sloppy so that the sashes or sash 12 can be removed in a manner described hereafter.

As shown in FIGURES 1 and 2, stop member 89 has an inwardly projecting handle 84 provided with a downwardly facing exposed surface which can be manually engaged to raise sash 12 towards its closed position.

The distance between handles 74 and stop member 80, when the bolts lare resting on fasteners 24, is equal to the width or diameter of one of the fasteners so that by pinching handles 74, as by grasping them between the thumb and the index finger, the bolts can be moved towards each other a distance sufiiciently great so that the ends of bolts 63 and 76 clear the line of fasteners. When pinched towards each other so that handles 74 engage stop member 86, bolts 68 and 70 clear fasteners 24 to permit the raising and lowering of sash 12.

The length of slot 76 and the distance between handles '74 is such that upon removal of stop member 80, the handles can be moved into engagement with each other so that the ends of the bolts move out of between flanges 3S and 40 to disengage the bolts from the frame. When thus disengaged, if sash 12 is closed or nearly closed, the upper end of the sash can be pivoted inwardly and raised so as to clear the top frame element 20 and remove the sash. The sloppy clearance between sash 12 and 14 permits this.

Thus, bolts 68. and 70 perform the dual function of retaining the upper end of sash 12 in the frame and of supporting the frame in a plurality of predetermined positions and the positions of these bolts control removal of the sash and adjustment of its vertical position.

While only a single embodiment has been shown, it will be apparent to those skilled in the art that many changes can be made in the details and arrangements of parts without departing from the scope of the invention as defined in the appended claims.
